After work we hopped on our mountain bikes and headed toward Bear Creek Lake Park to ride the Mt. Carbon Loop.  On the way, we saw a few people gathered by the side of Bear Creek Trail, looking at something.  Turns out it was a snapping turtle:

Leaves are now budding out everywhere and a few flowering trees have begun to bloom.  On one stretch of the Mt. Carbon Loop, the wild plums have blossomed, giving off an intoxicating scent.  We also saw the nesting Great Horned Owl along the Cottonwood Trail and at least one owlet.

I received another email from the Bird Banding Laboratory.  I’d sent a second picture of the band on our resident female Red-tailed Hawk.  Here are the two pictures with partially legible numbers:

Here is the response:

Thank you for your patience and thank you for the additional photo. I have re-searched our database for 1957-XX651, and unfortunately, I still cannot rule out several individuals banded in California. Please let me know if you happen to get either or both of the last digits.

At the noon hour I took a walk in the Bear Creek Greenbelt.  Bear Creek was still running high, for the third day in a row.  About a week ago my better half and I watched someone–a Lakewood employee, perhaps–open up the gate on a ditch that leads off Bear Creek (just east of the footbridge between Estes and Old Kipling).  The ditch began running higher than we’d eve seen it.  Then two days ago, Bear Creek began running high, as though someone had opened up the dam at Bear Creek Lake Park.   We’d never seen the current moving so fast.  We weren’t alone in wondering whether Mallard nests on low-lying areas near the edge of the creek were getting flooded.

After work I took another walk in the greenbelt, and Bear Creek, though still high, was no longer running fast.  Maybe the spigot at the dam has been tightened.

Then I turned and headed east and explored a little of the greenbelt east of Estes.  The Great Horned Owl was “sleeping” sentry:

I got word that the nest is indeed nearby and that there are three owlets, none of which can be readily seen.

Just across the creek I got my first look this year at a Swainson’s Hawk in the greenbelt:

Back on the west side of Estes I caught sight of this Belted Kingfisher:

Also–yesterday I saw the first-of-year Broad-tailed Hummingbird at the nectar feeder on our back deck.

This morning I took a walk in the Bear Creek Greenbelt shortly after dawn.  I saw Yellow-rumped Warblers in the treetops (which is where American Goldfinches, in their spring plumage, are being seen these days).

Song Sparrows perch lower, sing loudly, and are more easily photographed:

At the pond that never freezes I saw two beavers, including this one:


A good assortment of waterfowl was out:  a female Hooded Merganser, a male Cinnamon Teal, three Blue-winged Teals (two males and one female), a pair of Gadwalls, a pair of Canada Geese, and Mallards.

In the afternoon in the greenbelt I saw a couple of Bushtits.  Here’s one:


At first there was one Double-crested Cormorant:

And then there were two:

And the Red-tailed Hawk pair:

This morning on our walk with the dog in the Bear Creek Greenbelt the Red-winged Blackbirds were the most populous, and vocal, of the species we saw.

There’s still a variety of waterfowl:  Mallards, Canada Geese, Gadwalls, Cinnamon Teals, Blue-winged Teals, a Double-crested Cormorant, and a couple of female Hooded Mergansers, including this one:

The female Red-tailed Hawk was on the nest at Yale.  The male was on one of their favorite perches:

At midway we rode our mountain bikes at Bear Creek Lake Park.  The Great Horned Owl was on her nest along the Cottonwood Tail, and we’re pretty sure we saw a white downy head next to her.

The temperature soared into the upper 70s today.  I took another walk in the greenbelt in the afternoon.  The darker-headed Red-tailed Hawk was on the nest:

A pair of Gadwalls:


The birds below may or may not have been yawning.  The Double-crested Cormorant was definitely doing some gular fluttering on the warmest day of the year so far.

This morning I joined a birdwalk at Chatfield State Park led by Joey Kellner.  The weather was beautiful, the company genial, and the birding pretty good!

Birds weren’t the only wildlife we saw:


Mule deer

We saw several Bald Eagles, including these two immature individuals:

We saw several shorebirds, including Greater Yellowlegs, a Semipalmated Plover, a number of sandpipers (including Western Sandpiper) and this Marbled Godwit:

There were also Blue-winged Teals, Mallards, Redheads, and Northern Shovelers . . . and White Pelicans.

We saw a nesting Great Horned Owl and a Long-eared Owl on the wing.  Here’s a Townsend’s Solitaire:

I saw my first-of-year hummingbird, Loggerhead Shrike, and Yellow-rumped Warblers (both Audubon and Myrtle).

In the afternoon my better half and I took the dog for a walk in the Bear Creek Greenbelt.  There were five Cinnamon Teals west of the footbridge (a single female), as well as a pair of Blue-winged Teals and a pair of Gadwalls.


We saw three Yellow-rumped Warblers flitting on the south bank of Bear Creek–both Audubon and Myrtle.

In the pond that never freezes two female Hooded Mergansers were curled up on a log:

The darker-headed Red-tailed Hawk was sitting on the nest at Yale.  Four Common Grackles were displaying in what appears to be a kind of lek.  One by one, each would spread its wings and vocalize:

For the first time ever, we saw an Osprey flying over the greenbelt.

When we got home, our neighbors were working in their back yard.  One said she thought she heard a Broad-tailed Hummingbird earlier today.  I’ve had my feeder up for almost ten days (I change the nectar regularly), but haven’t seen one on our back deck yet.

April 23, 2021

On our early morning walk in the Bear Creek Greenbelt we saw the first Black-crowned Night Heron of the year . . . just where I expected it to show up, which is in the marsh east of the pond that never freezes.

In the afternoon we saw several teals, including these three:

Cinnamon Teal (male) and two females (Cinnamon and Blue-winged)

The female Red-tailed Hawk was at the nest:

Late this afternoon my better half and I took the dog for a walk in the Bear Creek Greenbelt.  We saw half a dozen Red-tailed Hawks, including this immature one that showed up along Bear Creek:

Cinnamon Teals and Blue-winged Teals were swimming in the creek, along with manky Mallard:

My better half and I walked the dog at the dawn hour in the Bear Creek Greenbelt.  We saw three beavers near the footbridge.  One was working on the dam, one was swimming with a tree branch back to the lodge, and one was sitting on a log.

On an early lunch walk in the greenbelt by myself I saw a pair of Blue-winged Teals by the footbridge:

A couple of Cinnamon Teals were nearby.  Here’s one:

The manky Mallard was quacking very loudly, as is her wont.

At the pond that never freezes a lone female Hooded Merganser and I quietly watched each other for several minutes.

I spotted my first Lincoln’s Sparrow ever:

Snow began to fall in the late afternoon.  An American Goldfinch showed up as a bright spot of color:

A few inches of snow fell overnight.  This snow was a lot drier than the last snowfall, which caused trees and branches to come down.  Early this morning, the temperature just below 20 degrees, we headed into the Bear Creek Greenbelt to see what we could see.  A lot of coyote tracks!  On every singletrack trail we walked on, we saw evidence of at least one coyote.  We also saw four Cinnamon Teals (three males and a female), a pair of Blue-winged Teals, and several Mallards.

This afternoon when we went for a walk, much of the snow had melted–even though the temperature was still under 40 degrees.  Here’s a male Cooper’s Hawk just after a meal:

This morning I went back to Bear Creek Lake Park, hoping to be like the early bird:

In the afternoon I took a long walk in the Bear Creek Greenbelt.  A Cooper’s Hawk was at work on the nest:
